The Stone Which The Builders Rejected
"12:10 And have ye not read this scripture; The stone which the builders rejected is become the head of the corner" (Mark 12:10 KJV) applies not only to the people of Judah who rejected the Messiah when He came in that time. It applies more to the "churches" that have since claimed to be Christian, while ignoring the Words of the Christ, which begin at Genesis, not Matthew (see Christ The Creator and The 'God Of The Old Testament'; also Why Did Christ Put Moses To Death?) i.e. many Christian-professing preachers, some of which even have university degrees in man's "theology" (see Doctorates Of Error; also What Rises To The Top?) have never even read the entire Holy Bible, the Word of God, while professing to be teachers of it. If they don't know what Christ said, having never even bothered to read it, how can they be true servants of The Lord? Answer - they can't. They are teaching merely the doctrines of men (see I Did It My Way).
"Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock"
The parable of the vineyard speaks clearly of how the Owner's vineyard, that was planted to produce Good Fruit, has been, for the most part, misappropriated by man-made doctrines and traditions. It was to those Christian-professing people that Christ also spoke of with "7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.7:22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? 7:23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity. 7:24 Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock" (Matthew 7:21-24).
"12:1 And he began to speak unto them by parables. A certain man planted a vineyard, and set an hedge [see Hedges] about it, and digged a place for the winefat, and built a tower, and let it out to husbandmen, and went into a far country. 12:2 And at the season he sent to the husbandmen [see Husbandman] a servant, that he might receive from the husbandmen of the fruit of the vineyard.12:3 And they caught him, and beat him, and sent him away empty.12:4 And again he sent unto them another servant; and at him they cast stones [see Stoning], and wounded him in the head, and sent him away shamefully handled.12:5 And again he sent another; and him they killed, and many others; beating some, and killing some.
